If this perp escalated his assaults from getting local kids in his neighborhood, to picking up Jared (and maybe others) and assaulting him in his car and releasing to picking up Jacob and not releasing that shows a pattern of change. Why would he revisit a previous location? It seems it was in a pattern of escalation, where he may go to assault a boy may not be the same place he would dump a body. He seemed to like some excitement and possibility of getting caught by choosing boys out of a group for example and letting Jared out after he had seen him and his car. Very risky. He also seemed to vary his location so I think that he is unpredictable even though he was clearly escalating his behavior at the time.
